N-Viro® Technology

The technology used at Walker Environmental’s biosolids processing facilities is the patented N-Viro® process. In this process, alkaline admixtures (such as lime) are blended with dewatered biosolids and/or other organic wastes to produce valuable agricultural fertilizers. These fertilizers, sold under the N-Rich® name, can also used in land reclamation, soil manufacturing, yard waste co-composting and a variety of other beneficial applications.
